"He'll call that trickle-down. I call it Niagara Falls"

This quote by Jack Kemp is a referral to the financial policy of trickle-down economics, which is the concept that tax cuts for the rich will cause financial growth and success for all. Kemp is criticizing this policy, comparing it to Niagara Falls, which is an effective and outstanding waterfall. He is implying that trickle-down economics is not almost as powerful or effective as it is made out to be. He is recommending that the financial benefits of tax cuts for the rich do not drip down to the remainder of the population, but rather stay focused at the top. This quote is a criticism of trickle-down economics and a pointer that economic policies ought to be created to benefit everybody, not just the rich.
